SOLE-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 522,799, dated-Tilly 10,1894.

Application filed September 5,1893. Serial No. 'l84 836i (No model.)

To ctZZ whom it may concern.-

Be it known that I, JAMEs F. N OONAN, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Ohanneling Maghines, of which the following is a specificaion. i

This invention has for its object to provide an improved machine, primarily for channeling boot and shoe soles, which can be readily adapted to perform feather edging and other operations.

The invention consists in the several improvementswhich I will now proceed to describe and claim.

Of the accompanying drawings, forming 'part of this specification: Figure 1 represents a side elevation of a channeling machine embodying my improvements. Fig. 2 represents an end elevation of the same. Fig. 3'represents a section on line 3-3 of Fig. 1, looking toward the right. Figs. 4 and 5 are elevations of the channel-cutter holder and the Fig. 6 represents a secelevations of the slide or block that supports the groove-cutter. Fig. 9 represents a sectional view'of'a part of a channeled sole.

The same letters of reference indicate the same parts in all the figures.

In the drawings: a represents the fixed part of the supporting-frame, having bearings for the shaft 1), which carries the work-supporting and feeding wheel 0.

01 represents the pressure-wheel, which is affixed to the shaft 6, the latter being journaled in bearings in the movable part a of the supporting-frame. Said movable part a, which I hereinafter terma head, is pivotally connected at a with the frame a, so that the said head can swing vertically to raise and lower the parts carried by and connected with-it.

The head a may be raised by means of a treadle (not shown), a rod f connected with said treadle, a lever f connected at one end with said rod and pivoted at f 2 to the frame a, and a rod f bearing on the other end of the lever f and connected at f with the swinging head a.

Motion may be imparted to the shafts h e by means of a shaft g, journaledin the frame a and having a crank g and a gear 9 a gear g on the shaft 1) meshing with the gear g and a gear 9 on the shaft 6 meshing with the gear 9 01' represents a presser-foot, adjustably secured to the head a and standing beside the wheel (:1, said foot being arranged to bear on the upper side of the sole just in front of the point where thechannel-cutterand the groovecutter hereinafter described act on the sole. Thefoot d is formed 011 a shank (1 which is vertically adjustable on the head a.

A screw d, the head of which is engaged with a flange on the shank d (see Fig. 3) and l the threaded portion with a threaded socket in the head a, raises or lowers the shank or foot when rotated.

d represents a clamping-screw, engaged with a threaded socket in the head a and passing through a slot d in the shank (1 the head of said screw being formed to bear on the said shank.

7t represents the channel-cutter, the shank h of which is of dovetail form, and is inserted in a dovetail groove formed in a block or holder 2', and maybe secured in said groove by a set-screw h Said holder is formed on a cylindrical stud i, which is embraced by a split clamp j on a dovetail slide j. The clamp is adjusted to grasp or release the stud i, by means of a screw f. The slide j is horizontally movable in a dovetail guide, formed in a slide or holder 70, which isvertically movable between guides on the frame a, and is connected bya rod with the swinging head a. so that the cutter rises and falls with the head. The slide j is adjustable horizontally by means of a screw j the head of which is grooved to engage the edges of aslot a formed in a plate a affixed to the frame a. The engagement of said head with the slot permits the screw j to rotate and move up and down, but prevents it from moving endwise; so that; when the screw is rotated, the engagement of its threaded portion with a threaded socket in an ear 7' formed on the slide causes the slide to move endwise.

The channel-cutter h is arranged to project into the space between the feed-wheel and the pressure-wheel, and is enabled by the abovedescribed devices to be adj usted endwise, sidewise and vertically. An endwise adjusttoo cutter in a direction at right angles to the shaft 1). A vertical adjustment may be effected by loosening the set-screw k that secures the rod k to a socket k formed on the head a, raising or lowering said rod and with it the block In and the channel-cutter, and then tightening said screw. The cutter may be further adjusted by turning the stud 11' in the socketj, and thus swinging the cutter up or down and varyingthe angle of its cutting edge.

m represents the groove-cutter, which forms the groove 00 (see Fig. 9) in the channel as made in a sole x by the knife h. Said groovecutter is affixed to a dovetail holder m, which is fitted to move in a horizontal dovetail groove n in a block or slide it, and is rigidly secured to said slide by a set-screw n. The slide a is vertically movable between guides on the frame a, and is connected by a rod n with the head a, so that the groove-cutter, as well as the channel-cutter, moves vertically with the said head. The groove-cutter is made adjustable both endwise and vertically by the described devices. An endwise adjustment of said cutter, in a direction parallel with the shaft 19, may he efiected by moving the holder m in the slide it; while a vertical adjustment may be effected by loosening the set-screw n that secures the rod n to a socket n on the head a, and then raising or lowering said rod, the screw being subsequently tightened.

It will be seen that both the channel-cutter and the groove-cutter may be adjusted to suit a considerable variety of requirements, and that each may be adjusted independently of the other, the channel-cutter havingalateral movement toward and from the groove-cutter, in addition to the endwise and vertical movements. The slides and it may be moved upwardly, to raise the cutters h and m, by means of screw-rods p g, which are engaged with threaded sockets in the base of the frame a and bear at their upper ends against said blocks, as shown in Figs. 1 and 3. When either rod is rotated to give it an upward movement, the slide against which it bears is correspondingly raised- Springs 1" 8, surrounding the rods 19 q, are attached at their lower ends to the frame a, and at their upper ends respectively to the slides in n. Said springs exert a downward yielding pull on the slides 70 n, and through said slides and the rods k n on the head a and its attachments, so that the presser-wheel d, presserfoot d, channel-cutter h and groove-cutter m are all yieldingly held down by the springs as far as the adjustment of the rods p g permits, said rods acting as stops to limit the downward movement of the described parts by the springs, and as adjusting devices to raise the head and its attachments.

if represents a gage-roll,which rotates loosely on a stud affixed to the frame a, and pro ects upwardly from a curved fixed shoulder 16 011 said frame, said shoulder and gage-roll being at the inner side of the feed-Wheel. The presser-foot d and wheel at project somewhat below the upper end of the gage-rolLas shown in Fig. 1, and may be adjusted horizontally toward and from said gage-roll, by means of an adj usting-screw c (Fig. l), the head of which has flanges i) ii engaged with an ear a on the head a, while the threaded part of said screw is engaged with athreaded socket in the frame a. A slot a receiving the pivot a that connects the head a with the frame a, permits the horizontal adjustment of the head and of the wheel at and foot 06, which may be effected by rotating the screw 7). A slot at in the arm a, permits the required vertical movement of the head a independently of the screw '0.

Operation: The sole to be channeled is inserted between the feed-Wheel and presserwheel and foot, the inner edge of the sole bearing against the gage-roll t. The wheels 0 d are then rotated, and the sole is thus moved against the cutters h and m, until a channel of the desired length has been cut, the sole being then removed.

The machine constructed as described may be employed for feather-edging and other trimming operations, a cutter suited to the desired operation being substituted for the channel-cutter, and the groove-cutter removed, if desired.
